One or more metal salts of at least one of Co, Ni and/or Fe is dissolved/suspended in water. To the solution/suspension is added at least one hard constituent powder to form a slurry. The solvent is evaporated, preferably by spray drying, and the resultant powder is heat treated in a reducing atmosphere. As a result, a coated hard constituent powder is obtained which, after addition of a pressing agent, can be compacted and sintered according to standard practice. In addition to or instead of said salt of Co, Ni and/or Fe, a soluble salt of Mo and/or W can be used. |
